Brammo Gains Track Record Using Amber Composites Prepreg to Drop Weight

31 May 2011

The Brammo Empulse, an all-electric motorcycle won both races of the inaugural round of the TTXGP, a zero-emission race at the Infineon Raceway.

The Empulse's fastest lap time at Infineon Raceway was almost two seconds faster than last year's winning electric bike on the 2.5-mile track. Previous bikes had only used carbon fibre as a cosmetic application but this year Brammo created the seat assembly and tank from Amber Composites 8020 prepreg to significantly reduce the weight of the bike and increase performance.

“With the Amber Composites prepreg, we were able to shave 30% off the weight of the assembly versus the previous design,” said Brian Wismann, Director of Product Development at Brammo. “As an added bonus, the surface finish was so straight out of the mould that we didn’t have to clear coat or paint it, saving further weight.” Brammo and Amber have a long working relationship both on the Empulse RR as well as Brammo’s award winning commuter bike, the Enertia.
